The warmer a rattlesnake, the faster it vibrates its tail. [6] Rattlesnakes tail-vibrate faster than other snakes, with some individuals nearing or exceeding 90 rattles per second. [7] [8] This makes rattlesnake tail vibration one of the fastest sustained vertebrate movements—faster than the wingbeat of a hummingbird. The movement is possible ...
The snake detection theory, [1] [2] [3] also sometimes called the snake detection hypothesis, suggests that snakes have contributed to the evolution of primates' visual system. According to the theory, predatory pressure from snakes has selected individuals who are better able to recognize them, improving their survival chances and therefore ...
Birds were one of the first animal species tested on their number sense. A raven named Jacob was able to distinguish the number 5 across different tasks in the experiments by Otto Koehler. [ 5 ] Later experiments supported the claim of existence of a number sense in birds, with Alex , a grey parrot, able to label and comprehend labels for sets ...
They found that snakes experienced a burst of innovation early in their history and have evolved at a rate perhaps three to five times faster than their lizard cousins.
[141] [142] [143] Another incidence of play in birds has been filmed showing a corvid playing with a table tennis ball in partnership with a dog, a rare example of tool use for the purposes of play. [144] Blue jays, like other corvids, are highly curious and are considered intelligent birds. Young blue jays playfully snatch brightly coloured or ...
However, the research goes on to note that "to date, only a handful of snakes have been observed to hunt in groups, and coordination among them — or among any other group-hunting reptiles ...
Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [ 13 ] [ 14 ] though it does not appear that they assess prey animals based on their body temperature. [ 15 ]
Sea snake scales differ from that of terrestrial snakes because they are rugose and wrinkled. Male sea snakes scale rugosity is more developed than that of the female snakes. The male turtle headed sea snake, Emydocephalus annulatus, provides an interesting case study because of their unique scales. [35]
